Specification of Letters Patent.

FIRELESS COOKER.

Patented Apr. 19, 1916.

' Application filed September 4, 1909. Serial No. 516,193.

To all whom it may concern:

lie it known that I, JOHN WINTER, a citizen of the United States,residin at Goshen, in the county of Elkhart and tate of Indiana. haveinvented a new and useful Fireless Cooker, of which-the following is aspecification.

This invention relates to devices of. that type commonly known astireless cookers and its object is to provide a durable'and compactdevice of this character, the parts of which can be easily kept cleanand which does not include in its construction any wood, which tend torender a device of this character unsanitary after same has been usedfor some time.

Another object is to provide a cooker which can be opened during thecooking process without much loss of heat, the construction of thecooker being such as to retain the heat as long as the device is in upright position.

Another object is to provide a seal for preventing the circulation ofair between the cover and the base of the receptacle, said cover boingin the form of a jacket de-' signed to extend over and downward aroundthe utensil-receiving portion of the cooker.

lVith these and other objects in view, the invention consists in certainnovel details of construction and the combinations of parts hereinaftermore fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings z-Figure 1 is a perspective view of the completecooker, the cover or jacket being shown elevated above the Fig. 2 is acentral vertical section through the cooker and showing the jacket inposition on the base. Fig. 3 is a section on line A-B, Fig. 2, a portionof the base being broken away. Fig. 4 is a detail view of the fasteningmeans-employed for securing the jacket upon the base.

-Referring to the figures by characters of reference, 1 designates abase, preferably formed of zinc, having a filling 2 of heat insulatingmaterial, there being a tubular receptacle 3 arranged concentricallyupon the base and provided with a bottom 4 and an inner or false bottom5, between which is arranged heat insulating material such as indicatedat 6. The bottom 4 is connected cloth. pads or other absorbent parts tothe base in any preferred manner, as by means of fasteners 7 extendinbase. A circular channel 8 is formed in the top of the base andconcentric with receptacle '3. The rece tacle is provided with a jacket9 made up of an inner tubular member 10 and an outertubular member 11,said members being spaced apart and concentric with each other, therebeing a spacing ring 12 between the lower ends of the two mem bers andprovided with a circular rib 13 designed to be seated within the grooveor channel 8. Both of the members 10 and 11 are closed at their upperends, said ends being spaced apart and the space between the two membersbeing completelyfilled with a suitable heat-insulating material, such asindicated at 14. The external diameter of the receptacle 3 is less thanthe internal diameter of the inner member 10 of the jacket'so that whenthe jacket is in position over and around the receptacle, an air spaceis formed between. the jacket and receptacle, this air spacecommunicating with the interior of said receptacle at the upper endthereof. This is permissible in View of the fact that said receptacledoes not contact with the closed end of the inner member 10.;

Handles 15 of any suitable construction are preferably connected to theouter member 11 of the jacket 9 and constitute means through the wherebysaid jacket can be conveniently removed from the receptacle.

It is to be understood that the receptacle and the jacket can be of anypreferred cross sectional contour.

Any suitable fastening means may be em ployed for securing the jacket 9upon the base. 'VVhen the jacket and receptacle are cylindrical, thefastening means disclosed in the drawings are preferably utilized. Thisfastening meafis includes oppositely extending ears 16 arranged upon thelower portion of the jacket and extendingrlaterally th refrom, said earsbeing designed to move into engagement with a keeper 17 mounted on "thebase '1. Each keeper is formed of a" U- l. C t) shaped portion 18disposed in a vertical plane and sutiiciently long to permit one of thecars 16 to move therethrough. One arm of the U-shaped portion is securedto the base while the other arm merges into a laterally extendingretaining finger 19, one end of which is attached to the base in anysuitable manner. Each finger is so located that when cars 16 are shiftedthrough the Ushaped portions of the keepers, they will assume positionsbeneath the fingers and thus be held against upward movement relative tothe base. When the fastening devices are thus in engagement, the jacket9 is held firmly on the base and with the rib 13 seabed within thegroove or channel 8.

In using the device herein described the utensil containing the food tobe kept hot or cold is placed within the receptacle 3 and the jacket 9is then placed on the receptacle so as toseat the rib 13 in groove orchannel 8. Said jacket is then partly rotated to bring the ears 16 intoengagement with the finger 19 of the keepers. The jacket and base arethus locked together and the heat is retained by the insulating materialcontained within the jacket, within the base, and within the bottomportion of the receptacle. Any moisture condensing upon the inner member10 of the jacket will flow downward into the air space between themember 10 and the receptacle and will tend to seal the joint between thejacket and the base and thus positively prevent the passage oi airbetween the parts. When it is desired to inspect the contents of thereceptacle, the jacketis turned so as to become unlocked and then lifteda suilicient distance above the receptacle to render the contentsvisible. The elevated jacket will remain filled with hot or cold andwhen it is returned to closed position these gases will displace any airwhich may have entered the receptacle during the temporary openingthereof. The ti-ni icrature within the body will not, there- -lore, varyto an objectionable extent as a result of such inspectioi'i.

it will be noted that there are no parts of the device which will absorbmoisture and therefore the cooker will not become toul after being usedfor some time. The various parts can be quickly cleaned in the samemanner as an ordinary metal utensil and are, therefore, perfectlysanitary.

Although the base 1 has been shown and described as containing aninsulating inateriai, it is to be understood that, if preferred, thesame may be formed entirely of metal or any other material desired.

It is to be understood that various changes may be made in theconstruction and arrangement of the parts without departing from thespirit or sacrificing the advantages of the invention.

that is claimed is 1. A fireless cooker including a base, an upstandingtubular receptacle receiving portion fixed 'upon the base, an annularsealing groove within the baseand concentric with said upstandingportion, a tubular cover closed at the top and extending over and aroundthe fixed upstanding portion and spaced therefrom, the lower end of thecover bearing on the base and bridging the groove, and an outstandingannular projection upon the bottom of the cover and removably seatedwithin the groove, the annular space between the cover and theupstanding receptacle receiving portion being adapted to receive andhold condensed moisture to seal the cooker against the admission of airbetween the base and cover. t

Q. A tireless cooker including a base, an upstanding tubular receptaclereceiving portion fixed relative to the base, and a cover removablymounted on the base and extending around and over said upstanding portioand spacedtherefroin.

3. A tireless cooker including a base, a tubular upstanding receptaclereceiving portion fixed relative to the base, a cover resting upon thebase and extending over and around said upstanding portion to preventthe admission of air thereto, and cooperating means upon the base andcover for holding said cover spaced at all points from the upstandingportion.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.

JOHN WINTER.
